To (ZZZ whom it may concern:

Be it known that I, VINToN ESIssoN, a citizen of the United States, residing at Chicago, in'the county of Cook and State of Illinois, have invented new and useful Improvements in Corru ated Metal Ends for Railway Cars, of which the following is a specification.

This invention relates to improvements in end structures for railway cars and more particularly to sheet metal ends for freight cars. H

The end of a freight car is subject to very severe shocks and stresses on account of the tendency of the cargo to shift when the train starts and stops and in switching and also to the tendency of the superstructure of the car to weave while the train is in motion. To strengthen this type of car, ends have been constructed of one or more sheets or panels of metal, usually steel, which sheets or panels are formed with corrugations for rigidifying the structure to more readily meet impacts from without, cargo thrusts from within, and the racking strains from weaving.

It is the object of this invention to pro vide an end of the sheet metal type which is adaptable to either wooden car frames or all metal freight cars and that may be em ployed for strengthening gondola cars, box cars, or other similar cars.

it is a further object of this invention to provide the sheets or panels of the end with corrugations of particular contour that from their form and length are peculiarly adapted to meet the stresses and strains al ready described. lVhile the corrugations are preferably formed parallel, their relation to each other or their direction is immaterial.

lVhilc the preferred forms of this inven tion are illustrated upon the accompanying sheets of drawings, yet it isto be under stood that minor detail changes may be made without departing from the scope thereof.

In the drawings:

Fig. 1 is a View in end elevation of a box car illustrating an embodiment of this invention.

Fig, 2 is a view on line 22 of Fig; 1.

Serial No. 680,130.

Fig. 3 is a View in section taken on line 3-3 0f Fig; 2'. Y

Fig. 4 is a View in section taken on line H of Fig. 2 i

' Fig; 5 is a View in section taken on line 55 of Fig; 2. r 1 Fig. 6 is'a fragmentary View of the corner ofapanel. i

Fig. 7 is a sectional view taken on line 7-7 of Fig. 6 in the direction of the arrows with the parts beyond the line shown in per speetive;

The embodiment 'of this invention is illustrated inthe drawings asapplied to a boxcar andshowsthe end comprising two or more sheets or panels 1, preferably of pressed steel, which are attached to the corner posts,v end plate and end sill in the usual manner. Fig. 2 illustrates a means for attaching the panels to the wooden corner posts 2 by Hanging the ends of the panels and securing the flanges to. the posts.

A plurality of strengthening corrugations areformed in each panel which merge at their ends into the plane "of the panel so that the panel has a'flat marginal portion about its edges. I

The corrugations are pressed from either side of the sheet or panel and have a constant depth and width for the major portion of'theirlength and are provided with terminalportions so that the corrugations merge into the panel to form flat. margins. The enlargedsectional View in Fig. 3 shows each corrugation at the center as having flat main walls 5 equally spaced and substantially. perpendicular to the plane of the panel connected by flat portions 6 which lie ina plane parallel to the plane of the panel until merged into'the panel near each end,

as shown in 7, The fiat connecting number of corrugations to which the lining is secured. These blocks are tapered and beveled according to the form of corrugation in order that the wooden lining may be secured in a position parallel to the panel.

The corrugations form, in effect, beams having compression and tension members with the greatest strength at the center, where it should be, to resistcentrally con-j centrated or equally distributed loads, or impacts in this particular construction. The amount of metallocated at a distance from the neutral axis of the panel is constantly reduced from the center to the ends of the corrugations. The maximum stretching or drawing inof the plate in pressing is at the center and is constantly and proportionately reduced from the center to the ends of the corrugations. The compression and tension members are positioned away from the neutral axis of the panel and are connected by webs, the main walls. The compression and tension members, the oppositely disposed flat connecting portions, vary in width from the center to the ends and the angular relation of the webs to the plane of the panel varies from the perpendicular at the center in accordance with the width of the compression and tension members until all merge into the panel.

This is a division of my application Serial 7 No. 414,056, filed October 1, 1920, which matured into 1924:.
